A common-ground switched-capacitor multilevel inverter with extended input range for renewable energy applications

open access: yesInternational Journal of Electrical Power & Energy Systems
Multilevel inverters (MLIs) have emerged as a prominent front-end converter solution for renewable energy generation like photovoltaic (PV), fuel cell and wind turbine, owing to their low total harmonic distortion (THD) and high conversion efficiency ...

Circuit for clamping bridge overvoltages in voltage-fed quasi-Z-source converter [PDF]

open access: yes, 2016
Unlike the voltage source converter, the Z-source converter can boost as well as buck the input voltage. However, the presence of physically large components in the impedance network introduces large parasitic inductances into power device commutation ...

Disentangling Bulk and Surface Contributions to Charge and Discharge Fading in High‐Voltage LiCoO2

open access: yesAdvanced Functional Materials, EarlyView.
High‐voltage operation of LiCoO2 accelerates capacity fading through bulk and surface degradation. By introducing a LiTaO3 coating to selectively suppress surface degradation, bulk and surface contributions to charge and discharge fading are decoupled.

Novel family of quasi-Z-source DC/DC converters derived from current-fed push-pull converters

open access: yes, 2014
This paper is devoted to the step-up quasi-Z-source dc/dc push-pull converter family. The topologies in the family are derived from the isolated boost converter family by replacing input inductors with the quasi-Z-source network.
